The first flight of SpaceX’s Dragon capsule

For the second time in seven weeks, SpaceX, Telesat and SSL teamed up for a commercial satellite launch from Cape Canaveral early Monday, this time successfully deploying into orbit a high-power telecom payload developed in a joint venture with a Hong Kong-based company.

SpaceX launched Argentina’s SAOCOM 1B radar observation satellite from Cape Canaveral at 7:18 p.m. EDT (2318 GMT) Sunday. A Falcon 9 rocket headed toward the south on a trajectory hugging the Florida East Coast on the first flight into polar orbit from Cape Canaveral since 1969, and the first stage booster returned to the spaceport for an onshore landing minutes after liftoff.

United Launch Alliance’s next launch attempt for its Delta 4-Heavy rocket from Cape Canaveral with a top secret U.S. government spy satellite will be delayed to no earlier than early Tuesday.
